• ASP.NET 3.5 Stateless Session Managment and connection pooling?

  - by Norm

  I am designing an ASP.NET (3.5) web application that connects to a Rocket Software UniVerse database. I am in the planning stages right now and need some help in being pointed in the right direction. I am brand new to ASP and C#. I am shooting for a RESTful design and a MVC pattern. Rocket provides a .NET library called UniObjects.NET which handles everything for connecting and retrieving information from the database. What would be the best way to in general to log my users into the database, then use that session via connection pooling? I see that in 3.5 there is the ASP.NET Routing Infrastructure and that looks promising am I in the right direction on this? Also does C# support decorators like Python and Java?

• why don't more programming languages have builtin interfaces to the window manager?

  - by Naveen

  Programming is at the heart about automating tasks on a computer. Presumably those tasks would normally be done manually by a human. Humans use the computer through the keyboard, mouse, and interaction with the console or the window manager. But very few languages have built in functions that provide an interface to these basic computing objects. A notable exception is autohotkey, an open source language on windows, providing builtin functions that allow the following simple tasks: * Get Pixel Information * Get mouse position * Keyboard macros * Simulate key strokes * Simulate mouse click * Window management See examples on rosettacode. There have been various attempts on linux, many of which were stopped without explanation. One is the inactive tcl library: android. Search google code for android, lang:tcl

• WebClient.DownloadString() Not Producing Exact HTML

  - by Ryan Fuentes

  So here's the deal. I'm creating a spider bot for a website that scans all the product pages and records the product data. I'm using C# and the WebClient library to download the HTML string. The site I'm crawling must be specially made because the HTML that is received from WebClient.DownloadString() is different than the HTML that I get when I view the source of the HTML when visiting it on a browser. This seems intentional because the only info I can't get is the price. Does anyone know a workaround for this problem or can anyone explain what is happening? Thanks.

• Enable GD support in PHP

  - by Don

  Hi, I'm trying to install pixelpost on an Apache server on windows. The installer is failing because: Pixelpost will not run if your PHP installation is not compiled with the GD graphics library. I've added the following line to php.ini extension=php_gd2.dll But I still get the same error message. When I run phpinfo() I don't see any reference to GD, so I guess it really isn't installed. I searched for php_gd2.dll and it's in the ext subfolder of my PHP root dir. I know nothing about PHP, so be gentle with me. Thanks, Don

• Is is possible to make a shaped, alpha-blended dialog?

  - by jgaa

  I'm making a non-rectangular dialog, modelled over an image from Photoshop (the image is the background of the dialog, and the user will see trough the transparent part of the image). I'ts like a dashboard-style window for a media-app with a few custom-drawn controls. Most of the background-image is either opaque or 100% transparent - but in between there is a thin area of partially transparent pixels, ment to blend the image smootly into the background. This works great for web-graphics, but I have not found a way to make this work for Windows windows. I'm using the Windows Template Library (WTL), msvc 2008 - and the app must run on Windows XP as well as Vista and Windows 7. Currently, I'm simply using the opaque part of the background-image to create a GDI clipping-region, but this gives pretty rough edges. Does anyone know about any API functions to accomplish this (part of WTL, or reachable from WTL)?

• Best canvas for drawing in wxPython?

  - by Pablo Rodriguez

  I have to draw a graph of elements composing a topological model of a physical network. There would be nodes and arches, and the latter could be unidirectional or bidirectional. I would like to capture the clicking events for the nodes and the arches (to select the element and show its properties somewhere), and the dragging events for the nodes (to move them around) and arches (to connect or disconnect elements). I've done some research and I've narrowed the alternatives down to OGL (Object Graphics Library) and FloatCanvas. I would not like to go down to the DrawingContext, but it is not discarded if necessary. Which canvas option would you choose?

• Crypto++ AES Decrypt how to?

  There are next to no noob guides to crypto++ out there. Or none that I've found anyway. What I want to do is decrypt an array of uchars I generate with another AES encrypter. Where would I start? I have the library built and linking grand. Do I need to set anything up or do I just call a function on my array (and if so what function) ? I'd really appreshiate some help from someone who knows this stuff. Thanks

• IOS SDK : first advices for beginners

  - by VdesmedT

  I too often answer the same kind of questions regarding basic topics like memory management, UITableView, Interface Orientation, MVC, etc... I understand very well that everyone starting with that SDK is too exited about getting its hand on it but a few reading would save them hours of debugging and the frustration that come along with the feeling that "We miss something here". I'd like experience users to share the few small articles, white papers, docs, book chapters that helps other save their time and avoid frustration. My first vote would be for : IOS Memory Management Guide View Controller Programming Guide Table View Guide And as a General recommendation, read the Overview section that come along with every class documention in the reference library, they contains most of what you need to know to avoid big traps !

• Why do my WPF UIElements NOT have OnPreview events?

  - by Matt.M

  I'm building a custom Silverlight UserControl which needs to listen to events using Preview/Tunneling, but for some reason the compiler is telling me they are not recognized or accessible. For example, I can add an event handler to MouseLeftButtonDown, but not PreviewMouseLeftButtonDown. This doesn't make sense because according to Microsoft (http://msdn.microsoft.com/en-us/library/system.windows.uielement_members(v=VS.100).aspx) all UIElements should have Preview events attached. Any ideas as to why this is happening? I'm using Visual Studio 2010 Trial, Blend 4 RC and .Net 4, if that makes a difference.

• How can I program ksh93 to use bash autocompletion?

  - by Norman Ramsey

  In a comment in response to a shell question, user tinkertim said that it was easy to hack ksh to use the bash autocompletion library. I would like nothing better than to use bash autocompletion with AT&T ksh93. How can this be done? ksh93 has a new release several times a year, so I am looking for a solution that does not involve modifying the source code. ksh93 can link new C modules dynamically and also is highly programmable (I run a ksh function at every keystroke), so modifying the source should not really be necessary. Note: I am not talking about filename autocompletion, which is easy to do in ksh. I'm talking about all the other yummy autocompletion stuff that bash does, like autocompletion options for nmh commands or autocompleting Mercurial commmands. Stuff like that.

• What's Your favorite f# use? where does f# makes life (a lot) easier (compared to c#)?

  - by luckyluke

  I've skimmed the stack and did not get the overflow as there is probably no such question. I'm just learning f# and I am A seasoned c# and .net dev. I am into financial apps and currently F# helps me a lot with maths calcs like zero finding or minimum finding (although I still want some good maths library there). I see that processing multiple items (files or smth) tends to be easier, but my GUI (web, win) are still c# based. I am in the team of 5 devs and we know that the new tool is out, we are learning it after hours (to pimp ourselves up) but maybe we shouldn't bash the door somebody already opened. So in business apps, whats Your first killer part of soft You would code in F# (if You could and would know IT would be easier, faster, more testable, easier to maintain etc.? Business rules? ImageProcessing? Data processing? hope it's not to subjective. luke

• penetration of web 2.0 features amongst users?

  - by user151841

  I have a survey web-app that is public facing. I want to set up automated testing with Selenium, but selenium can't capture javascript alerts that we're currently using on the site. I'm thinking about changing our user-facing error notifications to some web 2.0 javascript library so that it is accessible to Selenium. However, I'm not sure how many of our users would be able to experience them properly. How backwards-compatible do I need to be in the present day? I have collected a database of actual user-agent strings of our users. I asked here how I could group them into meaningful data about what browsers our users are actually using.

• How do I handle user authorization the safest way?

  - by Irro

  I'm developing a small website where I'm going to allow user to create accounts but I'm quite clueless when it comes to safety around authorizations. I have built my project in PHP with codeigniter and found a library (Tank Auth) that could handle authorization for me. It stores password in a safe way but I'm still worried about the part when the user sends their password to my server. One easy way to do it would be to send the password in a post-request but I would guess that it's quite easy to sniff such a password. Should I do something with the password on the client side before sending it to my server? And is there any good javascript libraries for this?

• A Combinations of Items in Given List

  - by mecablaze

  Hello stackoverflow, I'm currently in Python land. This is what I need to do. I have already looked into the itertools library but it seems to only do permutations. I want to take an input list, like ['yahoo', 'wikipedia', 'freebase'] and generate every unique combination of one item with zero or more other items... ['yahoo', 'wikipedia', 'freebase'] ['yahoo', 'wikipedia'] ['yahoo', 'freebase'] ['wikipedia', 'freebase'] ['yahoo'] ['freebase'] ['wikipedia'] A few notes. Order does not matter and I am trying to design the method to take a list of any size. Also, is there a name for this kind of combination? Thanks for your help!

• Should I use a modified singleton design pattern that only allows one reference to its instance?

  - by Graham

  Hi, I have a class that would normally just generate factory objects, however this class should only used once throughout the program in once specifix place. What is the best design pattern to use in this instance? I throught that having a modified singleton design which only allows one reference to instance throughout the program would be the correct way to go. So only the first call to getInstance() returns the factory library. Is this a good or bad idea? Have I missed out another fundermental design pattern for solving this problem? Thanks for your help.

• Optimising Androidplot

  - by Zammbi

  Seems Androidplot (androidplot.com) website/forums are down so I'll try asking this question here. I have multi touch zoom and scrolling. Similar code to http://mlepicki.com/2012/03/androidplot-multitouch-zoom-scroll/ except that I have a bar graph instead. However with 100 data points it has noticeable lag. Even with 10 bars are just showing. Sounds like its drawing/calculating/etc all bars. Any idea on how I could optimise this? I can't use hardware rendering as I want to support Android 2.1 and the library doesn't support it(it breaks).

• AS3IsoLib New IsoSprite

  - by KoopaTroopa

  I'm following a guide (http://www.jsparrowhawk.com/blog/?p=75) on how to use the As3IsoLib library. It seems his examples are a little erroneous at times. I'm at the part of creating a sprite, assigning it an image and then rendering. When I test my application I get my box and grid but not the sprite. var mySprite:IsoSprite; mySprite = new IsoSprite(); mySprite.setSize(40, 40, 0); mySprite.moveTo(120, 40, 0); scene.addChild(mySprite); var myImgLoader:Loader = new Loader(); var myImgURL:URLRequest = new URLRequest("http://www.jsparrowhawk.com/blog/wp-content/uploads/2011/10/as3isolib_styling_6b.jpg"); myImgLoader.load(myImgURL); myImgLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, imgLoadComplete); function imgLoadComplete(e:Event):void { var myImg:Bitmap = new Bitmap(e.target.content.bitmapData); mySprite.sprites = [myImg]; scene.render(); }

• Get information about a function in python, looking at source code

  - by Werner

  Hi, the following code comes from the matplotlib gallery: #!/usr/bin/env python from pylab import * x = array([10, 8, 13, 9, 11, 14, 6, 4, 12, 7, 5]) y = array([8.04, 6.95, 7.58, 8.81, 8.33, 9.96, 7.24, 4.26, 10.84, 4.82, 5.68]) I am new to python, and would like to change the content of x and y from an input file. I have two short questions: I could guess what array means, but once I see it on the code, how can I know to which library it belongs and more information about it? Should I use some kind of python debug commands? How do I insert the content of my input file into x? Thanks

  I am trying to write a WPF windows application that dynamically creates a 3 D object for an existing 3D Image. The senerio is as follows. Mark the points randomly on the existing 3D Image. Create a 3D object based on the points already marked. Check the below Sample Screenshots. Screenshot 1 and Screenshot 2 I am successfully able to load the 3D file to the WPF form. And was able to perform the rotation using TrackballDecorator 3D Tools library. I have just read this related post. however i didn't get it exactly :) So,can you suggest some efficient methods to achieve it.
